It appears that alpacas (Vicuna pacos) can extend the useful life of a Christmas tree.
They like to eat them and then, when they are stripped of needles, the main stem can be tied to a pasture fence post where alpacas use them as scratching posts.
Here is a short video (45 s) from the BBC about this behavior.
